Specification of Letters Patent.

Application filed January 22, 1916. Serial No. 73,541.

To all whom it may concern:

Be it known that I, PATRICK H. McCooE, citizen of the United States, residing at Indiana Harbor, in the county of Lake and State of Indiana, have invented a certain new and useful Improvement in Anticreepers for Railway-Rails, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to anticreepers for railway-rails and in one of its aspects includes one clamping member having a portion for underlying the flange of a rail and terminating in upwardly projecting hooks and. a second clamping member adapted to engage the rail flange and movable transversely of the rail along the first aforesaid clampin member, these clamping members having mterengagement for preventing the movement of the second mentioned clamping member transversely of the other member, orlongitudinally of the track. 7

In accordance with another feature of my invention the inner upright faces of the aforesaid hooks in which one of the clamping members terminates slope one toward the other slightly. By this feature of the ,invention the wedging block may better per form its function; it bein received 1n the tapering spacin between t e rail flange and an adjacent hoo the clamping member carrying such hook yielding sufficiently to enable the key to be driven into position substantially to fill the spacing.

I will explain my invention more fully by reference to the accompan ing drawing showing the preferred embo iment thereof and in which Figure 1 is a plan view illustrating a device of my invention in place; Fig. 2 is a sectional plan view on line 2 2 of Fig. 5 Fig. 3 is a perspective view illustrating parts of the structure; Fig. 4 is another perspective view illustrating the device as applied to a rail; Fig. 5 is a sectional view on line 5 5 of Fig. 2; Fig. 6 is a horizontal section illustrating the sloping of one inner upright hook face with respect to the opposing upright hook face.

Like parts are indicated by similar characters of reference throughout the diiferent figures.

The track, of which shown, is supported in any ferred way upon ties, such a one of the rails a is usual or pre tie being indiceive one through this spacing,

cated at b. The rail illustrated'is usual type employing a head and a .base flange that are united by a vertical web. The clamp of my invention includes one member whose intermediate portion a underlies the base flange d of the rail section a to which the device is applied, the portion 0 extending transversely of the rail (preferably at right angles thereto) and terminating at its ends in hooks e and f which extend upwardly. The clamp member 0 has a tie abutting lug 0 depending therefrom and projecting beyond the same to engage the tie b. The hook e is shaped snugly to reside of the base flange, as illustrated in Fig. 4:, but the hook f is enlarged to receive the complemental clamp member g which is desirably provided with upper and lower insetting lips 71., i to'form a channe snugly receiving base flange. The top of the portion 0 leaves the bottom surface of the flange d where the lip i is disposed to afi'ford space to' receive such lip, as indicated in Fig. 3. The clam member 9 has such interengagement with the complemental clam the portion 0 thereo moved transversely ofthe other clamp member .uponany creepage of the track rails. This interengagement is desirably afforded by means of a tongue 70 which is'received within a slot formed by and intervening between the lips 5 having substantially the same width as the tongue and desirably provided in the base of the clamping member 9. This slot divides the lip 71 into two parts between which the tongue 70 is received, both of these parts of this lip engaging the tongue whereby creepage of the clamping member g longitudinally of the track and transversely of the complemental clamping member is prevented. Instead of constituting the clamping member 9 a wedge, I desirably make the upright part thereof that engages the edge of the rail flange cl of uniform thickness. I actuate the clamping member 9' by a wedging key m which is received within spacing that intervenes between the clamping member g and the upright part of the hook f. The key is driven into position the inner face of the upright art of the hook f sloping slightly toward t e opposed inner face of the upright part of the hook 6 whereby the channel way that receives the key is tapered the better to enable said key to force the clamp member 9 member (preferably,

of the a l the contiguous side of the v that it cannot be 4 againstthe rail flange d. Theportion c ef the other clamping member will flexlor bend sufliciently in the plane in which it lies to enable the key m to find its way through the spacing between the clam ing member 9' and the inner face of the upright lportion of the hook f, the wing m being t ereafter bent over. The clamp moved by the key m, the tongue lc having only such engagement with the clamp member g as to prevent longitudinal movement of this clamp member with respect to the track while the two parts of the lip 2' have efl'ective engagement only with the tongue It for this same purpose.

When the device for preventing the creeping of the rail is in place spacing intervenes forme between the lug c and the base of the rail and this lug projects beyond the main body portion of the clamp member 0 into engagement with the tie b. If the rail moves or tends to move toward the tie the lug 0 will turn or tend to turn the clamp in the plane of the rail base thereby increasing the grip of the clamp upon the rail base to overcome the tendency to creep. If the rail should move or tend to move in the reverse direction the fixed relation of the clamp and rail would not be disturbed. By referring particularly to Figs. 1 and 5 it will be seen that the to of the hook f overlies the channel fore also'fiverlies the part of the rail base that is received in this channel whereby the top of the hook I holds the lip 'h from being warped out of position when the rail tends.

to rock or cant. By providing two lips that are spaced apart at their inner ends, the tongue k may be roperly received therebetween without e ectively interfering with the function of the lower jaw of the clamp by the separated lips i. The tonguek is also engagedwith the bottom of the rail base. That is the lower rail engaging side of the clamp member g is, for all practical purposes, as long and as effective as the upper side it of this clam member.

The tops of both hooks a and are thus approached closely enough to the rail;

member 9 is free to be clamping member between the l1ps k and i and there-.

overlie the space that receives the base of to While I have herein shown and particularly described the preferred embodiment of my invention I do not wish tobe limited to the precise details of construction shown as changes may readily be made without-departing from the spirit of my invention, but having thus described my invention I claim as new and desire to secure by Letters Patent the following.

anticreeper for railway rails including one clamping member having a portion 0 for underlying the base of -a rail and terminating in upwardly projecting hooks e and f whose tops overlie the space that receives the base of a rail; a second clamping member 9 adapted to engage the base of therail and movable transversely of the rail along the first clamping member, this second aving the top lip 12. and two separated bottom lips z, the clamp portion 0 being recessed to receive the lips z and having a tongue 70 passing into the space between the lips z to prevent the second clamping member 9 from moving longitudinally of the rail whose base is engaged by and between the lips k and 91 while resting upon the clamping portion 0, the top of the hook f overlying the channel formed by the lips 71. and i and thereby overlying the base of a rail that is received in this channel; a key m interposed between the upright portion of the hook f and the adjacent face of the clamping member 9 to force this clamping member into engagement with the base of the rail; and a tie abutting lug depending from the clamp portion a and projecting beyond the same to afford a space between a tie engaged by said lug and the clamp portion 0.

In witness whereof, I hereunto subscribe my name this seventeenth day of January A. 1)., 1916.
